Work to do:The last table is too complicated to render in $\LaTeX$; a diagram in progress (discuss) You can help $\mathsf{Pr} \infty \mathsf{fWiki}$ by completing it. When this has been done, the template should be removed from the code.

BOOK IV THE TRILITERAL DIAGRAM

Chapter I Symbols and Cells

Change of Biliteral into Triliteral Diagram

The $xy$-Class subdivided into the $xym$-Class and the $xym'$-Class

The Inner and Outer Cells of the North-West Quarter assigned to these Classes

The $xy'$-Class, the $x'y$-Class, and the $x'y'$-Class similarly subdivided

The Inner and Outer Cells of the North-East, the South-West, and the South-East Quarters similarly assigned

The Inner Square and the Outer Border have thus been assigned to the $m$-Class and the $m'$-Class

Rules for anding readily the Compartment, or Cell, assigned to any given Attribute or Attributes

Table IV. Attributes of Classes, and Compartments, or Cells, assigned to them

Method of translating a Proposition from concrete into abstract form

Two forms of Problems

$[\S 2]$ Given a Pair of Propositions of Relation, which contain between them a pair of codivisional Classes, and which are proposed as Premisses: to ascertain what Conclusion, if any, is consequent from them

Rules

Examples worked fully

The same worked briefly, as models

$[\S 3]$ Given a Trio of Propositions of Relation, of which every two contain a Pair of codivisional Classes, and which are proposed as a Syllogism: to ascertain whether the proposed Conclusion is consequent from the proposed Premisses, and, if so, whether it is complete
